font
The font CSS shorthand property sets all the different properties of an element’s font. Alternatively, it sets an element’s font to a system font.
Try it
As with any shorthand property, any individual value that is not specified is set to its corresponding initial value (possibly overriding values previously set using non-shorthand properties). Though not directly settable by font , the longhands font-size-adjust and font-kerning are also reset to their initial values.
Constituent properties
This property is a shorthand for the following CSS properties:
Syntax
The font property may be specified as either a single keyword, which will select a system font, or as a shorthand for various font-related properties.
If font is specified as a system keyword, it must be one of: caption , icon , menu , message-box , small-caption , status-bar .
If font is specified as a shorthand for several font-related properties, then:
- it must include values for:
- it may optionally include values for:
- font-style , font-variant and font-weight must precede font-size
- font-variant may only specify the values defined in CSS 2.1, that is normal and small-caps
- font-stretch may only be a single keyword value.
- line-height must immediately follow font-size , preceded by «/», like this: » 16px/3 «
- font-family must be the last value specified.
Values
System font values

font-weight
Устанавливает насыщенность шрифта. Значение устанавливается от 100 до 900 с шагом 100. Сверхсветлое начертание, которое может отобразить браузер, имеет значение 100, а сверхжирное — 900. Нормальное начертание шрифта (которое установлено по умолчанию) эквивалентно 400, стандартный полужирный текст — значению 700.
Синтаксис
Значения
Насыщенность шрифта задаётся с помощью ключевых слов: bold — полужирное начертание, normal — нормальное начертание. Также допустимо использовать условные единицы от 100 до 900. Значения bolder и lighter изменяют жирность относительно насыщенности родителя, соответственно, в большую и меньшую сторону.

Браузеры обычно не могут адекватно показать требуемую насыщенность шрифта, поэтому переключаются между значениями bold , normal и lighter . На практике же начертание в браузерах обычно ограничено всего двумя вариантами: нормальное начертание и жирное начертание.
